Sludge conditioner

Abstract

The invention relates to the field of sludge treatment equipment and particularly relates to a sludge conditioner. The sludge conditioner includes a feeding spiral conveyor, a conveying mechanism anda discharging spiral conveyor. The conveying mechanism includes a driving component, a feeding component, a conveying component, a transmitting component and a plurality of stirring components. The driving component is arranged on one side of the conveying component and the two are in transmission connection. The feeding component is arranged on an upper end of the conveying component. The transmitting component is arranged on the other end of the conveying component. The plurality of stirring components are circumferentially distributed in the conveying component. Each stirring component is in transmission connection with the conveying component through the transmitting component. A holding component is arranged right below the conveying component. When in use, the sludge conditioner disclosed by the invention can work continuously, thus improving conditioning efficiency of sludge. And during a conditioning process, separated sludge can be filtered out, reducing work amount during subsequent dewatering work. The sludge conditioner of the invention can also reduce labor intensity of equipment, prolonging the service life thereof.

Description

technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a sludge conditioning device. Background technique [0002] A large amount of sludge will be produced in industrial production and sewage treatment, and these sludges will contain a large amount of water and organic matter. In order to improve the utilization rate of resources and reduce the impact of sludge on the environment, it is necessary to conduct in-depth sludge Dewatering, so that the water content of the sludge is less than 60%. In order to improve the dehydration performance of sludge, the sludge must be treated in the early stage, which is what we call "sludge conditioning".  The sludge is tempered before sludge dehydration to change the physical and chemical properties of sludge particles, destroy its colloidal structure, and reduce its affinity with water, thereby improving the dehydration performance of sludge. A commonly used method for sludge conditioni...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned patent can realize automatic mixing of sludge and sludge conditioner, there are following deficiencies in actual use. First, the device needs to mix sludge and sludge conditioner in batches, each Quantitative work is required every time. During work, other sludge cannot continue to enter the equipment, and continuous work cannot be achieved, thereby reducing the mixing efficiency of sludge and sludge conditioner. Second, due to the high density of sludge, it will Increase the difficulty of stirring, and when the above-mentioned device is in use, it directly uses the motor to drive the stirring rod to stir the sludge, which is more difficult to work and increases the load of the motor, which will affect the service life of the equipment
